Based on this, it is possible to obtain a sensing value corresponding to the aforementioned added size.

In FIG. 4A , a metal 410a may be directly or indirectly connected to one end of the display module 460 (eg, the display module 160 of FIG. 1 ). An internal substrate of an electronic device (eg, the electronic device 101 of FIG. 1 ) may include a plurality of metals 420a spaced apart from each other along one axis (eg, the x-axis).

The metal 410a may be moved along one axis (eg, the x-axis) when the size of the area shown on the display module 460 changes. As described above, since the metals 420a disposed on the substrate are spaced apart from each other, the capacitance due to the capacitive coupling between the

metals

410a and 420a may vary depending on the size change of the visible area. . The display length detection module 430a may sense a capacitance value due to the capacitive coupling formed between the aforementioned metal 410a and the metals 420a. The capacitance value may be interpreted as a value corresponding to the one-axis length (eg, x-axis length) of the added portion compared to the basic size in the display module 460 .

In FIG. 4B , a metal 410b may be connected to one end of the display module 460 . A coil 420b formed long along one axis (eg, the x-axis) may be disposed on an internal substrate of the electronic device. An inductive coupling may be formed between the metal 410b connected to the display module 460 directly or indirectly and the coil 420b disposed on the substrate. The metal 410b may be moved along one axis (eg, the x-axis) when the size of the area shown on the display module 460 changes. The display length detection module 430b may sense an inductance value due to the inductive coupling formed between the aforementioned metal 410b and the coil 420b. The inductance value may be interpreted as a value corresponding to the one-axis length (eg, x-axis length) of the added portion compared to the basic size in the display module 460 . However, the present invention is not limited thereto, and the display length detection module 430b may recognize a change in magnetic flux of the magnetized metal 410b or detect a change in rotation of magnetic flux within a hinge of an electronic device.

In FIG. 4C , the display length detection module 430c may be directly or indirectly connected to one end of the display module 460 . The display length detection module 430c may be a hall sensor. One or more magnets 420c may be disposed on an inner substrate of the electronic device. According to the size change of the visible area, the distance between the display length detection module 430c and the magnet 420c may change, and the magnetic flux sensed by the display length detection module 430c may change. The magnetic flux value and/or the magnetic flux pattern sensed by the display length detection module 430c may be interpreted as a value corresponding to the uniaxial length (eg, x-axis length) of the added portion compared to the basic size in the display module 460 .

In FIG. 4D , the housing of the electronic device may include a conductor 410d disposed to contact the touch screen panel of the display module 460 . Illustratively, the conductor 410d is shown as contacting the curved portion of the display panel, but is not limited thereto. When the size of the area shown on the display module 460 changes, the contact position between the conductor 410d and the touch screen panel may change. The display length detection module may sense contact coordinates between the conductor 410d and the touch screen panel as a sensing value.

In FIG. 4E , a resistance strip 420e and a wiper 410e connected directly or indirectly may be connected to one end of the display module 460 . The resistance strip 420e may be formed long along one axis (eg, the x-axis) of the internal substrate of the electronic device. A resistance value may vary according to a contact point between the wiper 410e and the resistance strip 420e. The display length detection module may sense the resistance value as a sensing value corresponding to the added area of the visible area.

In FIG. 4F , a device 410f may be directly or indirectly connected to one end of the display module 460 . The instrument 410f may reflect the signal transmitted from the display length detection module 430f. The mechanism 410f may be moved along one axis (eg, the x-axis) according to a change in the size of the visible area. The display length detection module 430f may obtain a sensing value based on a signal reflected from the object 410f. For example, the display length detection module 430f transmits a signal (eg, light) toward the object 410f through a light source based on Time of Flight (TOF), and measures a time difference between a transmission signal and a reception signal. can A time difference (eg, phase difference) between a transmitted signal and a received signal may be converted into a distance. However, the present invention is not limited thereto, and the display length detection module 430f may measure the amount of reflected light. A light quantity may be converted into a distance. The distance between the display length detection module 430f and the fixture 410f may correspond to the length of one axis (eg, the length of the x axis) of the area added in the visible area. For example, when the distance between the display length detection module 430f and the object 410f increases, the uniaxial length of the area added in the visible area may increase. For another example, when the distance between the display length detection module 430f and the object 410f decreases, the uniaxial length of the added area in the visible area may decrease.

Fig. 5 is a flow chart showing an operating method of an electronic device according to an exemplary embodiment.

In operation 510, the electronic device (eg, the electronic device 101 of FIG. 1 or the processor 120 of FIG. 1 ) receives a first signal received from at least one sensor module (eg, the sensor module 176 of FIG. 1 ). A first graphic element corresponding to the first direction information calculated based on the sensed value may be output to a display module (eg, the display module 160 of FIG. 1 ). The graphic element may include at least one of a direction graphic representation indicating a direction from the electronic device toward an object or true north, and a location graphic representation indicating a location of the object. The directional graphic representation may be output at a display reference point within the application screen of the visible area. The application screen may represent a screen of an application providing graphic elements based on direction information. The application screen may occupy the entire area or a partial area of the displayed area. The display reference point may be a point indicating the position of the electronic device within the application screen. The location graphic representation may be output at a point indicating an object within the application screen, which is determined based on direction information with respect to the display reference point. The first sensing value may be obtained based on sensing before occurrence of an event for changing the size of a visible area, which will be described later.

In operation 520, the electronic device may monitor a change in relative position between the first graphic element being output and the at least one sensor module in response to an event for changing the size of the visible area of the display module. The event for changing the size of the displayed area may be a user input causing a size change of the displayed area, an event for changing the display size received through communication, and/or a display size change triggered by an application. At least one of the events may be included. A relative position between the graphic element (eg, the first graphic element) and the sensor module may be a relative position between a display reference point and a sensing reference point.

For example, the sensing reference point may be a physical location of a sensor module. The sensor module may be moved or fixed within the electronic device according to the structure of the electronic device when the size of the area to be viewed changes. The display reference point may be moved by a change in the area and/or location of the application screen based on a change in the size of the displayed area, or may be moved by a change in a point representing the location of the electronic device within the application screen.

In operation 530, when it is determined that the relative position has changed, the electronic device may correct second direction information calculated based on the second sensing value received from at least one sensor module based on the change in relative position. . For example, the electronic device may correct the second direction information when a relative position (eg, distance) between the sensing reference point and the display reference point changes. The second sensed value may be a value obtained after a sensing time of the first sensed value, and may be a value sensed after a size change of the visible area starts. For example, the second sensing value may have a different value from the first sensing value when at least one sensor module moves due to a change in the size of the visible area. For another example, the second sensing value may have the same value as the first sensing value when the position of at least one sensor module is fixed. The electronic device may correct the second direction information by performing at least one of recalculating the second direction information, calculating and applying a correction value to the second direction information, and applying a previously recorded correction value to the second direction information. there is.

In FIGS. 6 to 8 , an example in which the position of the sensor module (eg, a sensing reference point) is fixed and the position of a graphic element (eg, a display reference point) in an application screen moves according to a change in size of a visible area is described. In FIGS. 9 to 11 , an example in which a sensing reference point is moved and a display reference point is fixed according to a change in size of a visible area will be described. In FIG. 12 , an example in which both the sensing reference point and the display reference point are moved according to the size change of the visible area is described.

In operation 540, the electronic device may output a second graphic element corresponding to the corrected second direction information to the display module. For example, the electronic device may output a second graphic element obtained by rotating and/or moving the first graphic element based on corrected second direction information.

In the above-described operations, an example in which a relative position is changed has been mainly described. Based on the relative position being maintained, the electronic device may output the second graphic element to the display module by using the second direction information calculated based on the second sensed value. When there is no change in the relative position, the electronic device may output the second graphic element using the second direction information without correction.

An electronic device according to an exemplary embodiment may execute an application providing a service related to the location of a local object (eg, a local object search service). For example, the electronic device uses augmented reality (AR) to display a camera image captured by an application and/or a camera module that outputs a graphic element corresponding to direction information without an image and a graphic element corresponding to an object together. You can run your application. In the augmented reality application, a graphic element corresponding to an object may be output at a position within the application screen determined based on a short-range positioning (eg, distance and direction) between the electronic device and the object. The electronic device may output a direction and/or distance toward an external location (eg, the location of an object and/or true north) through a graphic element at a point (eg, a display reference point) corresponding to its own location in an application screen. For another example, the electronic device may output a graphic element at a point in the application screen corresponding to the distance and direction representing the position of the object on the camera image.

When the position of the electronic device changes according to its own movement, the electronic device may remeasure direction information and distance or perform correction according to the amount of movement. In addition, the electronic device may correct the sensed second direction information corresponding to the change in size of the area shown on the display module based on a change in relative position between the sensor module and the graphic element. Therefore, the electronic device can output the graphic element indicating the external position without error by correcting the change of the sensing reference point according to the movement of the sensor module and/or the change of the display reference point according to the movement of the graphic element to the second direction information.

6 to 8 illustrate correction of direction information and output of graphic elements when a display reference point is moved while a sensing reference point is fixed in an electronic device according to an exemplary embodiment. .

While the electronic device (eg, the electronic device 101 of FIG. 1 or the processor 120 of FIG. 1 ) does not detect (or generate or receive) an event for changing the size of the region 760 shown on the display module, A first sensed value of a sensor module (eg, the sensor module 176 of FIG. 1 ) may be obtained. The electronic device may determine first direction information indicating a direction from the first display reference point 711 toward an external location based on the first sensed value. The first display reference point 711 is a point within the visible area 760 serving as an output standard for graphic elements before the size of the visible area 760 is changed, and may be a point indicating the location of an electronic device.

In operation 610, the electronic device may detect (or confirm or receive) an event for changing the size of the visible area 760 while the sensor module is fixed. For example, the electronic device may detect a size change of the visible area 760 caused by driving a motor and/or an external force.

In operation 620, the electronic device may acquire the changed size of the visible area 760. For example, when the electronic device changes the size of the visible region 760 by driving a motor, the electronic device may change the size of the visible region 760 based on motor driving information (eg, the number of revolutions of the motor and the change length per revolution). The size to be changed (eg, uniaxial length) of 760 can be predicted. For another example, the electronic device may obtain an added size (eg, added length) compared to the basic size (eg, basic length) in the visible area 760 based on the sensing of the display length detection module. In the visible area 760, the length added to the basic length may also be referred to as the extended length e. For example, the electronic device may obtain an extended length e corresponding to the added area of the visible area 760 .

In operation 630, the electronic device may calculate a movement length s of a graphic element (eg, a direction graphic expression). For example, the electronic device may calculate the movement length s of the first graphic element according to the size change of the visible area 760 . The electronic device may determine the movement length s of the display reference point based on the changed size obtained in operation 620 described above. The second display reference point 712 is a display reference point after the size change of the visible area 760 is completed, and may be a point moved from the first display reference point 711 by a movement length s. In the example shown in FIG. 7 , the display reference point is located at the center point on one axis (eg, the x-axis) of the application screen and can be moved by half of the extension length e described above. The electronic device may determine half of the extension length e as the movement length s of the display reference point. The directional graphic expression output from the display reference point may also be moved by the movement length s.

According to the comparative embodiment, the points 721 at which the positional graphic representations determined based on the first direction information are displayed at the second display reference point 712 indicate the physical position of the real object 790 from the second display reference point 712. You can deviate from the line corresponding to the direction you are facing. In addition, an error may occur in a direction indicated by a direction graphic expression displayed at the second display reference point 712 as well as a position error of the points 721 on which the location graphic representations are displayed. In the comparative embodiment, the first direction information based on the first sensed value of the sensor module and the second direction information based on the second sensed value are the same, but an error may occur because the display reference point has changed. In the comparative example, an error corresponding to a positional difference (eg, movement length s) between the second display reference point 712 and the first display reference point 711 may occur. Since the movement length s increases as the extension length e increases, an error between the second direction information without correction and the direction toward the real object 790 may increase. For convenience of explanation, an example in which the visible area 760 of the display module is expanded has been mainly described, but is not limited thereto. In the comparative example, a similar error may occur even when the size of the visible area 760 is reduced.

In operation 640, the electronic device may correct direction information based on the sensed value of the sensor module. An electronic device according to an exemplary embodiment may include a movement length s of a first graphic element (eg, a direction graphic representation), a distance D to a physical location corresponding to the first graphic element, and first direction information (eg, direction graphic representation). : Based on the angle a) between directions from the first display reference point 711 toward the external location on the basis of the x-axis, second direction information (eg, between the direction from the second display reference point 712 to the external location on the basis of the x-axis) The corrected angle b) can be corrected.

For example, the electronic device may determine one axis length (eg, x-axis length) d x and other axis length (eg, y-axis length) d between the object 790 and the first display reference point 711 based on the angle _a and the distance D. _y can be calculated. The electronic device may obtain the length of one axis d _x and the length of another axis d _y based on d _x =D×cos(a) and d _y =D×sin(a). The electronic device may calculate the corrected angle b based on b = tan ^-1 (d _y /(d _x +s)). As the size change amount of the visible area 760 increases, the movement length s of the display reference point may increase. A larger correction value may be applied to a graphic element corresponding to an object 790 displayed far from the display reference point along the y-axis within the application screen.

For another example, the electronic device may correct the second direction information using the calibration information. The calibration information may include a pre-calculated correction value for a sensing value of at least one sensor module. The calibration information may include correction values corresponding to movement lengths of a first graphic element (eg, a directional graphic expression disposed at a display reference point) with respect to a plurality of sensed values of at least one sensor module. Correction values of the calibration information may be pre-calculated and stored for each movement length, distances between the external location and the electronic device, and additional lengths compared to the basic length in the visible area 760 .

In operation 650, the electronic device may output a graphic element using the corrected direction information. For example, the electronic device may perform at least one of rotation in a first rotation direction and movement in a first movement direction of the first graphic element based on an increase in the visible area 760 with at least one sensor module fixed thereto. A second graphic element may be created by applying . For another example, the electronic device rotates the first graphic element in a second rotation direction different from the first rotation direction based on the reduction of the visible area 760 with the at least one sensor module fixed, and the first rotation direction. A second graphic element may be created by applying at least one of the movements in a second movement direction different from the movement direction. The electronic device outputs a second graphic element obtained by applying at least one of rotation by an angle corresponding to the size change amount of the visible area 760 and movement by a displacement corresponding to the size change amount to the first graphic element. can do. For example, in FIG. 7 , the electronic device may arrange and output a graphic representation of the location and direction of points 722 on a line corresponding to the corrected second direction information from the second display reference point 712 .

In FIG. 7, the correction of the positional direction graphic expression has been mainly described, but in FIG. 8, the correction of the direction graphic expression has been described. For example, the electronic device displays a first graphic element (eg, the first direction graphic representation 811) corresponding to the first direction information in response to an expansion event of the displayed area, a first size change amount of the displayed area. A second graphic element rotated by an angle corresponding to (eg, the second direction graphic expression 812) may be output. The electronic device may output a second direction graphic representation 822 obtained by rotating the first direction graphic representation 821 even when the visible area is expanded by a second size change amount greater than the first size change amount.

9 to 12 describe correction of direction information and output of graphic elements when a sensing reference point moves in an electronic device according to an exemplary embodiment.

In operation 910, the electronic device (e.g., electronic device 101 of FIG. 1, processor 120 of FIG. 1) moves the sensor module (e.g., sensor module 176 of FIG. 1) to the visible area. An event for changing the size of 1060 may be detected (or confirmed or received). Only the sensor module can be moved and the display reference point can be fixed, or the display reference point can be moved together with the sensor module. 9 to 11 describe an example in which the sensor module moves while the display reference point is fixed. 12 describes an example in which both the display reference point and the sensor module move.

In operation 920, the electronic device may acquire the changed size of the visible area 1060 while the position of the graphic element (eg, directional graphic expression) is fixed. The electronic device may determine the extended length e compared to the basic length in the visible area 1060 . An application screen guiding the direction of the object 1090 may be displayed in the basic area corresponding to the basic size of the visible area 1060 . A screen of another application may be displayed on the area added compared to the basic size. The size of the application screen for guiding the direction of the object 1090 may be maintained. The display reference point 1010 in the application screen may also be maintained. The display reference point 1010 is fixed, but the second direction information obtained after screen expansion may be different from the first direction information according to the movement of the sensor module.

In the comparative embodiment, the point 1031 determined based on the second direction information based on the second sensing value obtained at the changed second position 1022 of the sensor module is different from the point 1032 determined based on the first direction information. can As described above, since the size of the application screen and the display reference point 1010 have not changed, the location graphic representation representing the object 1090 must be displayed at the point 1032 determined based on the first direction information. The aforementioned error may increase as the movement amount of the sensor module increases. As described above, the directional graphic representation displayed at the display reference point 1010 should be maintained because the application screen is the same, but rotation due to the second direction information changed by the movement of the sensor module may cause an error.

In operation 930, the electronic device may stop sensing of the sensor module. For example, when the electronic device detects an event in which the sensor module moves from the first position 1021 to the second position 1022 while the display reference point 1010 is fixed, the electronic device deactivates the sensing of the sensor module. can do.

In operation 940, the electronic device may monitor rotation of the electronic device. The electronic device may monitor whether rotation of the electronic device at or above a threshold angle occurs in a display plane (eg, an xy plane) based on a 6-axis sensor (eg, an acceleration sensor and a gyro sensor). The electronic device may continue to stop sensing of the sensor module when the electronic device does not rotate beyond the critical angle. The electronic device may stop sensing of at least one sensor module while the at least one sensor module is moving by changing the size of the visible area 1060 . The electronic device may maintain a graphic element (eg, a position graphic expression and/or a direction graphic expression) displayed on the application screen by preventing the sensor module from acquiring the second sensed value. For example, the electronic device may display a second graphic element, such as the first graphic element, based on the movement of at least one sensor module by changing the size of the visible area 1060 while the position of the first graphic element is fixed. can output

In operation 950, the electronic device may correct direction information based on the sensed value of the sensor module. The electronic device may resume sensing of the sensor module when rotation of the threshold angle or more occurs (operation 940 - Yes). For example, the electronic device may record the correction value calculated based on the first direction information when the aforementioned event (eg, an event in which the sensor module moves while the display reference point is fixed) occurs. The electronic device may apply a correction value to second direction information obtained based on sensing of at least one sensor module.

For example, when an event occurs, the electronic device may calculate prediction direction information corresponding to a size changed by an event in the visible area 1060 . The predicted direction information may be direction information based on a predicted sensing value predicted to be sensed by the sensor module at the second position 1022 based on the point of time when the first direction information is sensed. The prediction direction information may include a prediction angle c formed between a direction from the second position 1022 toward the object 1090 and one axis (eg, the x-axis). The electronic device may obtain the length dx of one axis and the length _dy of another axis based on the angle a (eg, the initial angle) according to the first direction information and the distance _D between the object 1090 and the sensor module. The moving length s of the sensor module may be equal to the extended length e. The electronic device may calculate the predicted angle c based on c=tan ^-1 (d _y /(d _x +s)). The electronic device may calculate a correction value based on the predicted direction information and the first direction information. The electronic device may calculate a difference between the predicted angle c and the angle a according to the first direction information as a correction value. The electronic device may correct the second direction information by applying the calculated correction value to the second direction information acquired based on the second sensed value of the sensor module. For example, the electronic device may subtract the correction value calculated from the second direction information.

The electronic device may output the second graphic element using the corrected second direction information. The electronic device may output a location graphic representation at a point 1032 on a line corresponding to the corrected second direction information from the display reference point 1010 .

For example, as shown in FIG. 11 , the electronic device may output a graphic element based on a fixed display reference point 1110 despite screen expansion. For example, the electronic device may display a first graphic element (eg, first position graphic expression) at a point 1131 corresponding to the first direction information based on the first sensing value sensed by the sensing module at the first position 1121. ) can be output. The electronic device may correct the second direction information based on the second sensed value of the sensor module moved to the

second positions

1122 and 1123 by the expansion of the visible area 1060 . The electronic device may output the second position graphic representation at

points

1133 and 1135 corresponding to the corrected second direction information instead of

points

1132 and 1134 corresponding to the second direction information. When rotation less than the critical angle is maintained in the posture of the electronic device, points 1133 and 1135 corresponding to the corrected second direction information may be the same as points 1131 corresponding to the first direction information. In addition, the electronic device provides a direction graphic representation 1142 corresponding to second direction information (eg, second direction information before correction) based on the second sensed value of the sensor module moved by the expansion of the visible area 1060. Instead, a direction graphic representation 1143 corresponding to the corrected second direction information may be output. The direction graphic representation 1143 corresponding to the corrected second direction information may indicate the same direction as the direction graphic representation 1141 based on the first direction information. Accordingly, the electronic device may display the object at the same point as the existing display position by applying a correction value to the error-occurring second direction information.

12 illustrates an example in which both the sensor module and the display reference point move. The electronic device is based on the movement of the first graphic element (eg, direction graphic representation displayed at the display reference point) and at least one sensor module (eg, the sensor module 176 of FIG. 1) by changing the size of the visible area. Thus, prediction direction information corresponding to half of the size changed by the event in the visible area may be calculated. For example, the electronic device may determine the movement length s of the sensor module as half of the extension length e. This may be because the display reference point is moved by a length corresponding to half of the extension length e, so the error compared to the aforementioned exemplary embodiment in FIG. 10 is also reduced by half. The predicted direction information may include a predicted angle c formed between a direction from the moved position of the sensor module toward the object and one axis (eg, the x-axis). _The electronic device may obtain the length dx of one axis and the length dy of another axis based on the angle a (eg, the initial angle) according to the first direction information and the distance _D between the object and the sensor module. The electronic device may calculate the predicted angle c based on c=tan ^-1 (d _y /(d _x +s)). The electronic device may calculate a correction value based on the predicted direction information and the first direction information. The electronic device may calculate a difference between the predicted angle c and the angle a according to the first direction information as a correction value. The electronic device may apply a correction value to the second direction information.

The electronic device generates a first graphic element (eg, a first position graphic expression and/or a second position graphic expression) using first direction information based on a first sensing value sensed by a sensor module at a first position 1221. can be printed out. The electronic device may correct the second direction information based on the second sensing value sensed by the sensor module at the second position 1222 using the correction value described above. If there is no correction, the point 1231 and the direction 1241 based on the second direction information may include an error. The electronic device outputs a second position graphic representation at a point 1232 corresponding to the corrected second direction information and/or outputs a direction graphic representation indicating a direction 1242 corresponding to the corrected second direction information. can do one Therefore, when the sensor module moves along with the size change of the visible area, the electronic device measures the direction information through the sensor module and corrects the re-measured direction information based on the changed display reference point to determine the position of the object and/or the electronic device. A graphic element representing the direction may be displayed on the display module.

Below, when the camera module moves while displaying an object in an augmented reality image, an example of reflecting the displacement of the camera module to display the location of an object will be described.

At least one sensor module (eg, the sensor module 176 of FIG. 1 ) of the electronic device (eg, the electronic device 101 of FIG. 1 ) according to an exemplary embodiment is a camera module (eg, the camera module of FIG. 1 ( 180)). As shown in FIG. 13 , when the size of the displayed screen of the electronic device is changed, the camera module may be maintained at a fixed position 1320 or may be moved from a first position 1321 to a second position 1322 .

For example, when the first graphic element moves without moving the camera module, the electronic device adjusts a field of view (FOV) centered on a target object in an image obtained based on the camera module to crop the image. can output For another example, when the camera module moves, the electronic device crops an image with a field of view (FOV) determined based on a target object and a moving distance of the camera module in the camera image acquired based on the camera module. can output The electronic device may crop the camera image to the viewing angle shifted in the opposite direction to the moving direction of the camera module so that the targeted object is targeted at the center of the viewing angle. A pixel shift amount may vary according to the distance between the object and the electronic device and the moving distance of the camera module. The electronic device may determine a pixel shift amount based on the distance to the targeted object and/or the moving distance of the camera module, and crop the camera image at a viewing angle shifted by the determined pixel shift amount. The electronic device may track an object while minimizing or reducing object recognition included in the camera image (eg, recognition based on artificial intelligence analysis), and thus the amount of computation may be reduced.

The electronic device may output a graphic element (eg, a graphic representation of a position and/or a graphic representation of a direction) of a targeted object using direction information corrected as described above with reference to FIGS. 1 to 12 . The electronic device may generate an augmented reality image by overlaying a graphic element on the cropped image.

The electronic device may output an augmented reality image without a margin area. When there is no margin area, the display reference point is moved according to the size change of the visible area, and the size of the augmented reality image may also change. In the closed state 1371, the electronic device may crop a partial image corresponding to the first viewing angle 1361 corresponding to the aspect ratio of the closed state 1371 among the original camera images 1373. In the open state 1372, the electronic device may crop a partial image corresponding to the second viewing angle 1362 corresponding to the aspect ratio of the open state 1372 among the original camera images 1373. The second viewing angle 1362 may have a range that is wider horizontally and narrower vertically than the first viewing angle 1361 . Based on the movement of the camera module, the electronic device may shift the cropped region of the original camera image 1373 in a direction opposite to the movement direction of the camera module. The direction of movement of the camera module may be parallel to the direction of expansion and contraction of the viewing area.

For another example, the electronic device may output an augmented reality image of the same size despite a change in the size of the displayed screen area. In this case, the image size cropped from the original camera image may be maintained. The electronic device may output augmented reality images of the same size in the closed state 1381 and the open state 1382 . When the camera module moves while expanding the visible area, the electronic device may shift the cropped area from the original camera image from the first viewing angle area 1391 to the second viewing angle area 1392 . The second viewing angle area 1392 may be an area moved in a direction 1393 opposite to the moving direction of the camera module relative to the first viewing angle area 1391 .

The electronic device may provide a target object and graphic element in the central area of the application screen to the user regardless of the size change of the displayed screen area.

14 and 15 are diagrams illustrating a calibration operation for obtaining a correction value based on a user input in an electronic device according to exemplary embodiments.

In operation 1410, an electronic device (eg, the electronic device 101 of FIG. 1 or the processor 120 of FIG. 1 ) may detect (or confirm or receive) an event for changing the size of a visible area.

In operation 1420, the electronic device may initiate calibration of direction information. For example, the electronic device may calibrate direction information of at least one sensing module based on a user input. When there is an error between the graphic element output after changing the size of the visible area and the direction of the real object 1590, the electronic device may perform a calibration operation through a user input. The user input may indicate an input for selecting an object 1501 for initiation of calibration. When the electronic device detects an event for changing the size of a visible area, it may output an object 1501 for starting calibration.

In operation 1430, the electronic device may store acceleration information and/or gyro information at a start point during calibration. For another example, the electronic device may calculate and store calibration omnidirectional information based on sensor information (eg, acceleration information and gyro information) acquired at the start of calibration.

In operation 1440, the electronic device may be rotated by a user's manipulation. In calibration, the electronic device may monitor acceleration information and gyro information of the electronic device during calibration. For example, the electronic device may output a directional graphic representation 1510 for calibration at the display reference point. During the posture rotation of the electronic device described above, the electronic device may output a directional graphic representation 1510 in a fixed direction (eg, a direction facing the front along the y-axis of the electronic device) within the visible region. The electronic device can be rotated by the user until the orientation of the directional graphical representation 1510 matches the object 1590 .

For reference, the electronic device may output a display 1530 indicating that direction information is being corrected. In FIG. 15, an example in which the display 1530 is output while entering calibration has been described, but is not limited thereto. Illustratively, as described above with reference to FIGS. 1 to 14 , while the size of the visible area is being changed, an indication 1530 indicating that the direction information is being corrected is output, and the direction information may be automatically corrected.

In operation 1450, the electronic device may store acceleration information and/or gyro information upon completion of calibration. The electronic device may end the calibration in response to the user's end input upon determining that the adjusted directional graphic representation 1510 is oriented toward the real object 1590 . The end input may indicate an input for selecting the object 1520 for end of calibration. The electronic device may calculate and store direction information (eg, acceleration information and gyro information) after calibration based on sensor information acquired at the end of calibration.

In operation 1460, the electronic device may determine a correction value based on acceleration information and/or gyro information stored at the start and end of calibration. For example, the electronic device may determine a correction value for direction information based on acceleration information and gyro information acquired at the end of calibration. The electronic device determines directional information before calibration based on sensor information (eg, acceleration information and gyro information) acquired at the start of calibration, and directional information (eg, acceleration information and gyro information) after calibration based on sensor information obtained at the end of calibration. gyro information) can be determined. The electronic device may calculate a difference between direction information after calibration and direction information before calibration as a correction value. Direction information before and after calibration may be determined based on at least one of the aforementioned acceleration information, gyro information, and earth magnetic field value. As used herein, “based on” covers at least based on.

The electronic device may correct the second direction information by applying the calculated correction value to the second direction information based on the second sensed value of the sensor module. (eg see operation 1470 of FIG. 14)
